They all look beautiful. British fashion and style is very different than USA. British take into account season, family history and type of material decided before the occasion. The tradition in UK is the bride must wear something blue, hence her choice of blue shoes which were gifted to her. This is called STYLE and CLASS. You should do some research before you comment.
Makes one think that the Duke has an ex-girlfriend that isn’t taking his marriage well, at all. I thought it looked like a lovely wedding. Best wishes to them both.
And who died and put you in charge of what's fashionable or not? It is obvious that being an American ( going by your accent) you would be used to garish, over-the-top 'fashion' and not the understated STYLE of the British upper class. They have style, without trying too hard. You should learn from them.
I think their choice of clothes is showing that they are down to earth people, who don’t go crazy for ridiculously priced dresses. In fact they all looked lovely . My only criticism would be , that 2 bridesmaids were there to carry her train and vail . That poor girl was fighting a losing battle.
